Moderator Airhead Posted April 4, 2012 Moderator Share Posted April 4, 2012 most likely cause is the crank seal magneto side, you may see evidence of petrol / oil in the magneto behind the cover? Also check the condition of the carb to engine rubber duct and the tightness of the carb clamp Link to comment Share on other sites More sharing options...
